can I put 6 of them in a 20g tank with other fish?Cories are shoaling fish which need others of their own species - at least 6 of them.
right now I have
6 neon tetras
5 fancy guppies
3 red eye tetra
1 cory catfish ( its either a panda or bandit, not sure)
5 danios (not sure what type. they are on the smaller side. brown with a black stripe on the side.)
is it over-stocked?
